Well, I planned on ordering a couple tubes to try, but I couldn’t find 2 that I wanted to try, so I bought one of the riven carbon tubes. It sounds really good, but have not compared it to my chuckler yet, so we’ll see. The most important aspect to me is volume, but it has potential. Certainly overpriced for a tube, but if it ends up being a keeper, the cost doesn’t matter, tubes don’t wear out
I would be tempted to buy one of the cambium tubes, but I would wreck it, so I don’t think it would be a wise investment. Even if it was the best sounding tube on the planet, that doesn’t matter in my world, but volume does
